The map above has top, right, bottom, and left padding applied inside the viewport. The view&#39;s <code>fit</code> method is used to fit a geometry in the view with the same padding. The view&#39;s <code>centerOn</code> method is used to position a coordinate (Lausanne) at a specific pixel location (the center of the black box). <p>Use <code>Alt</code>+<code>Shift</code>+drag to rotate the map.</p></p>
